四、DEX保护壳分析
五、Native原理分析
六、总结
一、背景
最近朋友让我帮忙对他们银行APP进行黑盒分析,检测其安全性，探未知程序漏洞与安全性测试，提升业务整体安全能力，我拿到APP后进行安装抓包后发现都是加密传输的，用JEB进行反编译找数据组合的地方，发现APP用某加固了，所以有了此文。
二、整体框架
主要对DEX整体加密、DEX代码分离运行时解密还原，java方法native化，大致框架如下图2-1所示：
图2-1
三、SO保护壳分析
3.1、so层壳流程分析
壳入口点：

从壳入口点特征可以大致判断出是UPX，我尝试通过upx -d进行脱壳出现异常，修改特征为upx!还是不能正常脱壳，应该是被变异了，考虑通过IDA进行动态调试脱壳。
dump so
将断点断在linker中调用壳入口的地方，启动调试，如图3-1所示：
图3-1
壳执行完成将解压完代码在内存中dump出来，如图3-1-2所示
图3-1-2
3.2、so层壳脱壳与修复
修复Elf32_Off、修复shdr、修复phdr、修复重定位，如图3-2所示：
图3-2
修复后可以正常反编译，代码有ollvm混淆，字符串加密，如图3-2-1所示：
图3-2-1
四、DEX保护壳分析
4.1、Jni_onLoad
Jni_onLoad主要就是动态注册几个Native方法，代码如下：

注册的native方法：
l(Landroid/app/Application;Ljava/lang/String;)Z r(Landroid/app/Application;Ljava/lang/String;)Z ra(Landroid/app/Application;Ljava/lang/String;)Z b2b([BI)[B m(Ljava/lang/String;I)V sa(Ljava/lang/String;Ljava/lang/String;)V al(Ljava/lang/ClassLoader;Landroid/content/pm/ApplicationInfo;Ljava/lang/String;Ljava/lang/String;)Ljava/lang/ClassLoader;
4.2、java层到native层
在壳的java层重写了android.app.AppComponentFactory类的几个关键方法，其中instantiateClassLoader是比较核心的，它最终会走到Native方法al中。
@Override // android.app.AppComponentFactory @TargetApi(29) public ClassLoader instantiateClassLoader(ClassLoader arg4, ApplicationInfo arg5) { if(!this.supportInstantiateClassLoader) { File v1 = new File(arg5.dataDir, "files"); if(!v1.exists()) { v1.mkdirs(); } S.p_solutePath = v1.getAbsolutePath(); S.f_PackageCodePath = arg5.sourceDir; S.l(null); arg4 = N.al(arg4, arg5, this.packageName, this.orignAppName); // 调用native方法 arg5.className = this.orignAppName; this.supportInstantiateClassLoader = true; } if(S.l) { this.acf = this.getACF(arg4); return this.acf == null ? super.instantiateClassLoader(arg4, arg5) : this.acf.instantiateClassLoader(arg4, arg5); } return super.instantiateClassLoader(arg4, arg5); }
4.3、反调试
反射调用 isDebuggerConnected

被抽走后的指令存储格式：
6C C6 FF 03 37 1E 38 00 08 00 00 00 xxxxxxx Debug info 指令长度 指令
五、Native原理分析
主要是通过解析smali代码进行了通过JNI反射调用等价的语义转换,转为了C代码，执行时通过FindClass、GetStaticMethodID、GetMethodID、CallxxxMethod。
我是通过JNItrace来分析，如图5-1所示：
图5-1
六、总结
壳整体是指令抽取加方法native化二者结合，所有被抽走的指令还原后dump出来也能分析出80%左右的代码，其它被native化的用JNItrace配合分析，所以用该加固方案客户端代码安全性一般。接下来就可以继续进行APP渗透分析。
